I get an error that this method does not exist. Why is this happening? I used it in other renderscript examples. the only difference is that over there i had an RSSurfaceView, here, i set the result on a image view. Now how can i make it rotate? If i set the "direction" to 5, then it rotates right with 90degrees. If i try with "direction" = 4, it doesn't do anything. I took this from an example where it would rotate a mesh over and over again
